MACHINE FOR CUTTING MATERIAL FOR UIVIBRELLA OR PARASOL COVERS.

SPECIFICATION forming part of Letters Patent No. 262,522, dated August 8, 1882,

Application filed May 10, 1882. (No model.)

To all whom zt may concern:

Be it known that I, EDWIN WroKsTEAD, of Jersey City, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Machines for Cntting Materials for Umbrella and Parasol Covers, otl which the following is a specification.

The object of my improvement is to produce a machine of simple and cheap construction and susceptible of being easily used for cutting the flaring-shaped pieces of material which are used in making umbrella and parasol covers.

My improvement consists in the combination, with a suitable bed or support for the material to be cut, preferably consisting of aroller, of a roller carrying knives arranged approximately in the form of triangles, which are alternately reversed around the circumference of the roller, and are arranged with their length approximately parallel with the axis of the said roller. rlhe holders for the knives which form the bases or shorter sides of the triangles are adapted to be removed and replaced by others opposite different points in the length of the knives forming the longer sides of the triangles,and by this means I am enabled to readily adapt the machine for 'cuttin g different widths of fabric for larger or smaller covers with but little waste.

The improvement also consists in the combination, with a bed-roller and means for adj Listing it vertically, of a roller carrying knives arranged approximately in the form of alternately-reversed triangles and disposed around the circumference of the roller, and other rollers between which material passes 'to said knives.

In the accompanying drawings, Figure l is a front view of the machine embodying my improvement. Fig. 2 is an end view of the same, and Fig. 3 is a front view of a roller of modified form for carrying the knives.

Similar letters of reference designate correspending parts in all the gures.

A designates the frame of the machine, which may he of any desirable form and materials, and as here shown consists essentially ot' two side pieces of casting and connecting 5o cross-rails or stretchers.

B designates a table over which the material to be cut is fed.

C designates abed, here shown as consisting ofa roller, which may advantageously, be made of a number of disks of paper clamped side by side upon a shaft between two metal heads, as such a roller will present a very desirable surface for the knives to work upon. The journals of this roller are supported in bear-' ings C', which are arranged in housings in the 6o side pieces of the frame A and held in position by means of screws C2. These screws may obviously be manipulated to adjust the roller into different positions.

D designates a roller, which carries knives E F, whereby the material is cut. Its journals are supported in bearings in the side pieces ofthe frame A. As shown, it consists essentially of two heads, a, a series of bars, b, extending between them, and webs c, connect- 7o ing the bars. The bars b extend alternately at reverse `angles to the axis of the roller, and serve as holders for the knives E, whereby the sides of the pieces of material desired are cut. Screws d or other devices may serve to secure these knives in place. The webs c at'- ford supports for holders c, to which are secured the knives F, whereby the ends of the desired pieces ot' material are cut when it is necessary that they should be cut. The knives 8o F may be secured by screws g to their holders c, and these holders may be detachably secured to the webs c by means ot' screws 7L passing through lugs extending from them and entering the webs. 8 5

It is obvious thatknivesE of various lengths may be secured to the bars b, and that holders e, of suitable size, with attached knives F, may be secured to the webs c in such position that their knives F will occupy proper posi- 9o tions at different points in the length of the knives E. Thus pieces of material of different lengths may be cut in the same machine, for use in making umbrellas and parasols of different sizes and with but little waste. The knives F may be pinking-knives, if desirable, as shown; but they may be of any other suitable kinds.

As umbrellas and parasols are made in various styles, some quite flat, some quite eonroo vex, and some of a greater number of pieces of material than others because of the employment of a greater number of ribs, I prefer to make the roller D in a manner which will provide for adapting it to all these modifications. I have shown it in Fig. 3 modified to secure this end. Here the roller has a body of any suitable form admitting of the attachment by screws or otherwise ot' holders fi, Which are severally adapted to iit the body ot' the roller, and are approximately each of the shape ot' two of the longer sides ot' a triangle, corresponding approximately to the shape of the pieces ot' material to be cut. Knives E F are attached to these holders t' by screws or otherwise. Obviously all necessary modifications may be made with the use of a roller and holders made as just described.

The roller D is driven by means of a pinion, G, on a crank-shaft, H, meshing into a gear- Wheel, I, on one of the journals. Preferably the roller D and the bed-roller C are made to ltravel in unison by means of gear-wheels J K on their adjacent journals; but these may not be necessary in many cases.

Rollers L supported in open-top bearings L may be employed to keep the material to be cut in proper form to be eut. IVhen employed the material will be passed between them. The material may be guided by hand, or adjustable guides may be employed to guide it properly when of different Widths.

The machine may, in Whole or in part, be found useful for other purposes.

I may in some cases find it necessary to remove the roller D and substitute for it a roller of larger or smaller diameter, so as to enable me to eut pieces of material of different sizes. The bed-roller C may always be adjusted to a position to suit the knife-roller employed.

I do not claim broadly the combination ot' a bed-roller and a second roller With knives on its periphery, and I am aware that knives have been attached to the head of a press and used in conjunction with a reciprocating platen for cutting pieces for umbrella-covers.

What I claim as my invention, and desire to secure by Let-ters latent, is

1. rlhe combination, with a bed or support for material to be cut, of a roller carrying knives arranged approximately in the form of triangles which are alternately reversed around the circumference ofthe roller and are arranged with their lengths approximately parallel with the axis of the roller, substantially as specilied.

2. The combination, with a bed 0r support for material to be eut, of a roller carrying knives arranged approximately in the form of alternately-reversed triangles, and holders for the knives which are at the bases or shorter sides of the triangles, adapted to be removed and replaced by others opposite different points in the length of the knives forming the longer sides of the triangles, substantially as specitied.

3. The combination, with. a bed-roller and means for adjusting it vertically, of a roller carrying knives arranged approximately in vthe form of al ternately-reversed triangles and disposed around the circumference of the roller and other rollers, between which material passes to said knives, substantially as specitied.
